Japan is pushing for the International Whaling Commission to ease the reintroduction of commercial whaling, with Japan’s chief whaling negotiator telling the ABC they must discontinue disputeful coverage.

But Australia's Environment Minister, Josh Frydenberg, says at the meeting in Brazil in September, he will stop any moves to change the decision-making process to make it easier to kill whales.

Joji Morishita will take over as chair at the meeting, warning there must be major changes in order to break the deadlock between pro- and anti-whaling countries.
